Jurgen Klinsmann has given a few glimpses into the workings of his upcoming roster for the May and June games rapidly approaching.

The U.S. National Team coach said on Twitter today that the roster will be announced in two different segments, one for European-based players on May 15, and then again on May 20 for MLS players.

Complicating the issue is that potential national team defenders Clarence Goodson and Michael Parkhurst are both based in Denmark and have league games through May 23.

Klinsmann will call in 29 players in these two segments, but the roster will be trimmed down to 23 by the time the team heads to Jacksonville to play the first of their five-game stretch against Scotland.

The Orlando camp begins on May 15, leaving little time to analyze the European roster selections before practice starts. However, with the advance selection of European-based players, there will be a better indication of who Klinsmann may select from MLS, many of whom may have the opportunity to play one more game before he makes his decision.

The 10 day camp will show the mindset and tactics that Klinsmann is taking into World Cup Qualifying, and whether or not he was serious when he announced that the time for experimentation was over.

On May 26, the U.S. will face Scotland in Jacksonville, Florida. Friendlies against Brazil and Canada will follow over the next nine days, before World Cup Qualifying begins against Antigua and Barbuda on June 8, followed by Guatemala on June 12.
